Specification of Letters Patent.

Patented Nov. i i

Application filed October 29, 1908, Serial No. c6036.). Renewed November5, 1912. Serial No. "Milt-t vented certain newandnseit'ul Improve mentsin Vacuum and Water-Connections for Filter-Frames, of which thefollowing is a specification accompanied by drawings.

This invention relates to an improved vacuum and water connect-ion forvacuum filter frames, but is not limited thereto.

In its most complete and preferred form it provides interchangeableconnections that can be very quickly connected and disconnected. 7

It also provides a glass or transparent section by which the flow in thepipe can be seen.

I will for convenience describe the ii]- vention as applied toalternative vacuum and water connections. v

. Further objects of the invention will hereinafter appear and to all ofthese ends the invention consists of a device hereinafter fullydescribed and claimedin this specification and shown in the accompanyingdrawings, 1n ,wlnch Figure l is aside elevation of a filtcrframc andvacuum and water connections embodying the invention; Fig. 2 is an endelevation of the male and female unions for the vacuum connect1on';'Flg; 1s a longitudinal sectional side elevation on the line at, w of'Fig. 2; Fig. 4 is a side elevation of the protecting casing for thegage-glass; Fig. 5 is a. sectional side elevation of the male union forthe .water c o-nn-ection.

Referring to the drawings A represents a suitable filter' frame and B isthe pipe connection therefor to which suction or pressure maybe'applied. In this instance thepipe B isprovided with the interiorly'screw threaded end to which the female union 0 isadapted to be fitted.This female union C is adapted to' interchangeably receive either thevacuum connection T shown in Fig 3 or water connection V shown in Fig. 5as desired. The vacuum connection is adapted to be connected to the pumpD which discharges into the tank E when a vacuum is applied tothe'filter frame. If desired water from an elevated tank F under controlof valves as shown can be passed to'the pipe B directly through the sameconnection (the pump being re versed but it Wlll be seen that theinvention be swung through the arc of a circle. The,

bridle is provided with an interiorly'screw threaded socket K inwhich-is mounted a hand screw L. The end of the screw ispreferablyrounded at O to form a ball to which is secured the button P.This button is preferably provided with the fingers Q,

which are bent over the ball 0 to secure the button to the ball.preferably provided with a projecting or The but-ton is also convexportion R adapted to enter a recess or concave seat in the male union T,so that when the screw L is tightened up the male union is held firmlyin position on the female union.

The' male union for vacuum connections comprises the elbow T preferablyprovided with shoulder a adapted to be seated in the socket or recess Z)in the female union C. A gasket 0 is arranged between the two unions andpreferably a' gasket (Z is proil' idcd between the button P and theunion in this instance exterior-1y screw threaded at c and is adapted tobe connected to the nipple f by means of the protecting glass holder U.The nipple f is screw threaded to receive the glass holder, which holderis preferably in the form of a substantially tubular casting, open atthe sides'at g and having the connecting ribs 11 which connect the endsockets 7'. These sockets as shownare provided with squared or octagonalportions]; to receive .a pipe wrench.

The other end of the elbow T is shown The gage glass 7). is arrangedwithin the glass holder and over the ends of the gage glass are placedthe gaskets g and washer: which are compressed between the holder andthe union T and the nipple f, thereby forming a. tightc .ed 'joint. Thenipple f is adapted to be suitably connected to the pump D.
